Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.02783 |
| Opus 5 | $0.00006 | $0.01392 |
| Sonnet 5 | $0.00003 | $0.00557 |
| Haiku 4.5 | $0.00001 | $0.00278 |
Grade A, and why
roblox-game-development scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Roblox Game Development Skill
Description
Expert Roblox game developer specializing in Luau scripting, game mechanics, UI/UX design, and monetization strategies. Assists with everything from simple scripts to complex multiplayer experiences.
Resource Library
This skill includes a comprehensive collection of production-ready resources:
- 📜 Helper Scripts - Professional utility modules for data management, networking, UI, game flow, and audio
- 📋 Document Templates - Complete project documentation templates including Game Design Documents, Technical Specifications, Testing Plans, and Marketing Strategies
- 📚 Development Resources - Game templates, asset libraries, debugging guides, performance optimization tools, and quick reference materials
Core Capabilities
Luau Programming
- Modern Luau Features: Utilize type annotations, generics, the New Type Solver (general release), improved type inference/autocomplete, and performance optimizations
- Script Architecture: Implement clean, modular code with proper separation of concerns
- Performance Optimization: Write efficient scripts that handle large player counts
- Error Handling: Robust error management and debugging techniques
Luau Type System Updates
- New Type Solver: General release (no longer a Studio Beta); enabled by default for
nonstrictandnocheckmodes starting January 7, 2026 - Key Improvements: Better type inference, fewer false positives, stronger generics support, and improved autocomplete
- Legacy Solver Timeline: The legacy solver remains available through 2026, but it is slated for removal
- Migration Guidance: Most code works without changes, but a few edge cases may need explicit type annotations or cleanup
- Best Practices: Prefer explicit annotations on public APIs, use generics where appropriate, and lean on improved autocomplete for faster iteration
-- New Type Solver infers types more accurately
local function processPlayer(player: Player)
local name: string = player.Name -- inferred correctly
local team = player.Team -- Team? properly inferred
end

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

roblox-game-development is a skill published in the GitHub repository greedychipmunk/agent-skills (17 stars, last pushed 15d ago), licensed MIT. It adds 13 tokens to every session and 2,783 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
